摘要

Background on the Defense Meteorological Satellite Program (DMSP) is provided, updated for the Navy system and the Block 5-D spacecraft. Geometrical aspects of sunglint are described with nomograms for determining the distance from the subsatellite track to the Primary Specular Point (PSP). Various aspects of sunglint patterns with implications vis a vis determining sea state and low-level wind direction are illustrated and described. The meaning of anomalous gray shade patterns appearing in DMSP Very High Resolution (VHR) visual data is thoroughly explored with examples of each specific cause and suggestions for tactical use. Island and land barrier effects on sea state and atmospheric moisture are illustrated in a variety of different sunglint relationships.
